3,006 PointsI'm having difficulty parsing a JSON file onto a listview for a personal project
Background: I'm trying to parse a JSON file into a listview. I've been following the "Building the Weather app" and "listview &adapter" tutorials and trying to apply those lessons into my project
Problem: I'm at the parcelable section of the tutorial and I'm having difficultly applying it into my project. My project is different from the weather app because it only has one list and no buttons. I'm having trouble passing information from my adapter to the MainActivity and I would appreciate any advice. Thank you

Really all you need to do is store the resulting data a member variable in MainActivity and create the Adapter passing along the list of parsed data.

3,006 PointsHi Seth,
Thank you for the reply. So I will go ahead and declare member variables in MainActivity. I have already created an adapter class but how do I initialize the adapter in MainActivity?

56,413 PointsThere really isn't any difference in initializing the adapter in MainActivity or another Activity. You construct a new one with the list and context and set the ListView's adatper to it. The difference is in how you come by the list data, not how you use it.
